John 1:14, “The Word became flesh”
At the center of the Christian faith is the doctrine of the incarnation, which confesses that the Second Person of the Trinity has taken human nature to Himself, binding humanity to divinity “inconfusedly, unchangeably, indivisibly and inseparably” in perfect union to the Person of God the Son.
One of the implications of this central belief is that the Second Person of the Trinity has truly become a human at every stage of development. To put it bluntly, the Person of God the Son became a zygote (a fertilized egg). Yes, the personal GOD—who is Himself the ground and source of human personhood—was a diploid cell in the womb of the Virgin Mary.
When the Second Person of the Trinity binds a fertilized egg to Himself—truly becoming a fertilized egg just as much as you or I were once fertilized eggs—He declares that all fertilized eggs are persons.
Brothers and Sisters in Christ, if we confess that the Word became flesh (which is the essence of our faith and of created reality itself) then we must also confess that the diploid cell in Mary’s womb truly is the Person of God the Son….and if this is so, we cannot but confess that every zygote in every womb is equally a person.
